PUMP.

SPECIFICATION Yforming part of Letters Patent No. 779,499, dated January10, 1905.

Application filed March 31, 1903. Serial No. 150,419.

To all whom t may concern,.-

Be it known vthat I, BENJAMIN vWM. RICE, a citizen of the United States,residing at Payette, in the county of Oanyon and State of Idaho, haveinvented a new and useful Pump, of which the following is aspecification.

My invention is an improvement in pumps,

and has for its object the construction of a `ply is to be drawn.

simple apparatus whereby a vacuum is quickly produced and water is drawnupward into the chamber in which the vacuum is formed and subsequentlydischarged therefrom.

Briefly considered, the invention consists of an air-tight casingmounted on the upper end of a suction-pipe, said pipe extending downwardinto the water from which the sup- This casing has a valvecontrolleddischarge pipe or faucet. A fuelreservoir is connected with the cylinderand means provided for burning said fuel within the cylinder, therebyexhausting theoxygen in said chamber and creating, by forming a partialvacuum, a difference between the pressure within the chamber and thepressure of the atmosphere upon the body of water from which the supplyis drawn.

In the accompanying drawings, Figure 1 is a sectional view showing myimprovement as applied to a single-acting pump. Fig. 2 is a sectionalview showing my improvement as used in a double-acting pump.

In the above figures, A represents the suction-pipe of a pump, whichpipe may extend into a well, mine, hold of a vessel, or into any placefrom which water is to be lifted.

B represents a receptacle, preferably, though not necessarily,cylindrical in form. This receptacle is air-tight and is connected inany suitable manner with the upper end of the pipe A, which dischargesinto it. A checkvalve B', of any suitable construction, is ar'- rangedin such manner as to permit water to discharge from thel pipe into thereceptacle, but to prevent water from flowing from the receptacle backinto the pipe. In the lower part of the receptacle, which may be of anysuitable size, is arranged discharge-pipe B2, closed by a suitable valveoperated by a handle B3. Any suitable means may-be provided forintroducing a fuel-as, for example, gasolene-into the receptacle B, andany means may be employed to ignite said fuel, the Inost convenientmeans being an electric spark produced by an igniter B, any well-knownform of which may be used. A springpressed check-valve Bi is arranged inthe receptacle and is adapted to allow the escape of the products ofcombustion and also to relieve the walls of the receptacle from thestrain caused by the explosion of such a fuel as gasolene. The valve Bf,however, prevents the introduction of air into the receptacle, as anyoutside pressure tends to force it more lirmly in its seat.

In the operation of the pump above described a small amount of gasoleneis admitted into the receptacle and exploded by means of an electricspark,.and the combustion of such gas consumes the oxygen in thereceptacle, while the force of the explosion lifts the valve B'L and theproducts of combustion es-,

cape into the outer air, leaving a partial vacuum in the receptacle. Thevalve B' lifts and water is discharged from the pipe A into thereceptacle, from whence it can be drawn oil at any time through the pipeB2.

In `Fig. 2 the receptacle is divided into two compartments C C by meansof a central partition O2. The upper end ofthe pipe A connects with thelower end of a pipe-section C3, extending centrally into the lowerportion of the receptacle and having two apertures C" C" communicating,respectively, with compartments C O2, and a valve C is arranged in saidpipe and adapted to cover one of said openings at a time.Discharge-pipes D D lead from the respective compartments and are fittedby oppositely-formed valves, the stems D2 being connected by a valve-rodD3, so that when one valve is opened the other is closed. A suitablefuel-chamber E is arranged above the receptacle and is supplied with anysuitable explosive liquid or gas through a supply-pipe E'. Beneath thefuel-chamber are two smaller chambers E2 E3, each of which communicatesthrough pipes E7 ES with one of the compartments and contains ignitingdevices extending down into the upper portion of the compartments.Valve-controlled passages give communication between the smallerchambers E2 E3 and the chamber E, the valves Ei having their stems E5connected to the ends of a Walking-beam E, so that as one valve isopened the other is closed. Any desired means may be used for operatingthese valves. All oi' the valves mentioned may be connected and actuatedby common means or they may be separately manipulated. NV hen gas is ad-VInitted through the pipe E7 and exploded in panding gas will operatethe valve E", and the current Will be turned on either by hand orautomatically when the Water has been discharged. Valves F are arrangedin each cornpartment similar to the valves B4 and for the same purpose.

It is obvious that this invention can be utilized in many forms and thatthere are many changesthat can be made in same Without departing fromthe spirit of this invention.

No claim is made herein for any particular valve or speciiic form oi'igniting device.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-A rlhe combination with asuction-pipe, a receptacle at the upper end of the pipe, said receptaclebeing divided into compartments, a pipe connected to the upper end oi'the suction-pipe and extending into the lower portion of the receptacle,said pipe having apertures opening respectively into the variouscompartments, a valve arranged in said pipe and adapted to close saidopenings alternately, discharge-pipes leading from the compartments andprovided with oppositely-aeting valves, means connecting said valves,and means for admitting and igniting an explosive in the compartments.
